Tech startup investor SoftBank Group rose 1.73 and was the top contributer to Nikkei, while chiprelated shares Tokyo Electron and Advantest jumped 1.7 and 3.29, respetively.

Top 30 core Topix gainers were Daiichi Sankyo, up 2.59 , followed by Hoya.

Top underperformers among the Topix 30 were Keyence and Murata…
